Hmmm. It is rare that the script detects the wrong fence post, but
it can happen if the shortlogs are similar and the diffstats also
happen to match.

I don't suppose there's a set of layers that you can send me, or
point me at where I can do a few test runs ?

Outside of that, you can add the native sysroot to your path and
run kgit-s2q by hand, and see exactly why it is detecting the
wrong fence post patch (and hence skipping).

That script is looking at the patches, and then checking the branch
from the top down to see if a given patch is already on the branch.
Once it finds a patch that isn't on the branch, it declares it the
resume point and starts from there. So if you have patches with
similar shorlogs/diffstats, see about changing them to be unique
and the script shouldn't move through them, looking for the resume

In Yocto 2.0+ I ended up dropping the autoresume logic, since with
the matching logic I hinted at above, it was indeed possible to
shoot through the middle and resume from the wrong point.
